Active clinical trials for "Aortic Diseases"

The objective of this study is to assess the benefits of endovascular technique in terms of efficacy and safety of Valiant Thoracic Stent Graft with the Captivia Delivery System in the treatment of thoracic aortic disease, in a cohort of patients representative of the population treated under real-life conditions of use in France for up to 5 years.

This prospective study was designed to analyse the postoperative and long-term outcomes of total laparoscopic vs. open surgical repair of infra-renal abdominal aortic occlusive disease (AOD) and infra-renal aortic aneurysmal disease (AAA) in comparable groups of patients using a propensity analysis model.

This study involves a single family, including 1 patient, father, mother and sister. The patient presented with a new phenotype associating premature white hair, renal polycystosis, aortic dilation/dissection and lymphopenia. Samples were taken in order to identify the origin of the symptomatology highlighted in the index case. In addition, it was observed that mice invalidated for bcl-2, normal at birth and indistinguishable from control mice, showed, after one week, a phenotype similar to that observed in this patient. The overlap between the patient's main clinical signs (lymphopenia, white hair and polycystic renal disease) and the manifestations presented by the invalidated murine model for BCL2 suggests that its phenotype may be secondary to a Bcl-2 expression defect.

The goal of this observational study is to learn about the association between cardiac valve calcification and the 1-year mortality after lower-extremity amputation in diabetic patients. Diabetic patients requiring lower-extremity amputation were retrospectively studied. Preoperative detailed anamnesis was taken. Cardiac valve calcification was assessed using echocardiography at baseline. One-year follow-up was conducted and included clinical visits, hospital record assessment, and telephone reviews to obtain the survival status of patients. Researchers compare the survival group to the mortality group to study the relationship between the cardiac valve calcification and mortality.

Open elective abdominal aortic surgery is a high risk procedure involving clamping of the aorta. Indications include abdominal aortic aneurysm (AAA) or aortic occlusive disease (AOD) causing lower limb ischaemia. These patients are often regarded as one entity in postoperative study settings. However, previous studies indicate that risk profiles, inflammatory activity, and haemodynamic capacity may differ between these groups. The first aim of this study was to evaluate postoperative ICU-requirements after open elective abdominal aortic surgery, hypothesising that AAA-patients had longer ICU-stays and needed more mechanical ventilation or acute dialysis than did patients with AOD. The investigators see a relatively high incidence of postoperative acute kidney injury (AKI) following aortic surgery. Neutrophil Gelatinase Associated Lipocalcin (NGAL) may be useful in the early diagnosis of postopeative AKI. However, NGAL is also known as a marker of inflammatory activation. The ischaemia-reperfusion injury and subsequent inflammatory response to aortic cross clamping may per se induce a rise in NGAL despite intact renal function. Therefore NGAL may not be a reliable marker of AKI after AAS. The second aim of this study is to describe the changes in NGAL after AAS in patients with and without postoperative dialysis-dependent AKI.

Ultrasound (US) is widely used as a diagnostic tool in a hospital setting. In a medical department, diagnosis like heart failure or most kinds of heart diseases, hypervolemia, hypovolemia, pleural effusion, pericardial effusion, ascites, diseases in the gall bladder/bile tract, urine tract and venous thrombosis are common. US is the key diagnostic tool in these diagnosis, and on early diagnosis is crucial both on behalf of the patients well-being, and for hospital logistic reasons. The aim is to study the clinical use of pocket sized US as a screening diagnostic tool in an department of internal medicine. Method: All patients admitted (in certain preset periods) to Department of medicine will be screened with pocket sized US by expert user. Changes in diagnoses, as well as medications as a result of US screening will be the endpoints. US findings will be validated against standard echocardiography, or standard US/CT/MRI performed at the Radiological department. The aim is to study the clinical use of pocket sized US as a screening diagnostic tool in a department of cardiology. Method: All patients admitted (in certain preset periods) to Department of cardiology will be screened with pocket sized US for heart disease, pericardial and pleural effusion. Examinations by expert users. Specific findings could be myocardial dysfunction as heart failure, cardiomyopathies, regional dysfunction due to ischemia, valvular dysfunction, atrial enlargement, and pleural/pericardial effusion. Changes in diagnoses, as well as medications as a result of US screening will be the endpoints. US findings will be validated against standard echocardiography in all. As in 1), but examination by non-expert users compared to expert users.

The aim of this prospective, explorative study of noninvasive neuromonitoring was to search potential and practical methods associated with neurological outcome in the perioperative and immediate postoperative setting of surgery of the thoracic aorta. These methods include abbreviated EEG monitoring, near-infrared spectroscopy, transcranial Doppler ultrasound and biochemical markers associated with neuronal damage.

The purpose of this study is to evaluate the clinical outcomes of transcatheter aortic valve replacement (TAVR) in the Asian Pacific population

Reliable prediction of the preoperative risk is of crucial importance for patients undergoing vascular operations. The assessment of the metabolic equivalent of task (MET) is an easy clinical evaluation of the functional capacity of an individual. A MET is defined as the resting metabolic rate, that is the amount of the consumed oxygen at rest. According to the MET concept a patient would be considered as "fit for surgery" when the stairs of two flights can be climbed and the housework can be fully managed by oneself. Hypothesis: Patients with a functional capacity over 4 MET (fit for surgery) have less perioperative complications with the focus on cardiac pathology than patients with less than 4 MET during aortic operations. Patients and Method: Retrospective analysis of a single center unit of 296 patients undergoing open or endovascular aortic repair.

The aim of the study is to assess if venous distension in patients with aneurysmatic arteriopathy is higher compared to patients with peripheral arterial occlusive disease (PAOD) and in controls.
